The system includes a pistol grip having front and rear handles, a barrel containing an injectable fluid, and a bottle mount integrated with the barrel for receiving and securing a bottle holder, the bottle mount including a conduit running from a spike tip that punctures a bung of the bottle into the barrel. The system further includes a needle coupling attached to the barrel adapted to receive and secure a needle and a plunger for assisting in drawing an injectable fluid from a bottle into the barrel and for forcing the injectable fluid out of the barrel. A ratcheting mechanism incrementally advances a selectable ultra-low dose of injectable fluid out of the barrel upon a full stroke of the pistol grip. A full stroke is defined as advancing the plunger forward by squeezing the front and rear handles together until the ratcheting mechanism stops the plunger from further advancing yet still allows the front and rear handles to be fully squeezed. ## Claims ### Claim 1 An ultra-low dose injection delivery system comprising: a pistol grip having front and rear handles for actuating the ultra-low dose injection delivery system by squeezing the front and rear handles together; a barrel for containing an injectable fluid coupled with the pistol grip; a bottle mount integrated with the barrel for receiving and securing a bottle holder, the bottle mount including a conduit running from a spike tip that punctures a bung of the bottle into the barrel; a needle coupling attached to the barrel adapted to receive and secure a needle; a plunger for assisting in drawing an injectable fluid from a bottle secured in a bottle holder attached to the bottle mount into the barrel and for forcing the injectable fluid out of the barrel; and a ratcheting mechanism coupled with a housing for incrementally advancing an ultra-low dose of injectable fluid out of the barrel upon a full stroke of the pistol grip, wherein a full stroke of the pistol grip is defined as advancing the plunger forward dispensing a selected ultra-low dose of injectable fluid out of the barrel by squeezing the front and rear handles together until the ratcheting mechanism stops the plunger from further advancing yet still allows the front and rear handles to be fully squeezed. ### Claim 2 (depends on 1) The ultra-low dose injection delivery system of claim 1 wherein the front and rear handles of the pistol grip are pivot-ably coupled and the pistol grip further comprises a handle spring disposed between the front and rear handles. ### Claim 3 (depends on 2) The ultra-low dose injection delivery system of claim 2 wherein the barrel and the bottle mount are in substantially parallel alignment. ### Claim 4 (depends on 2) The ultra-low dose injection delivery system of claim 2 wherein the plunger is threaded along a substantial portion of its length. ### Claim 5 (depends on 4) The ultra-low dose injection delivery system of claim 4 wherein the ratcheting mechanism within the housing further comprises: a tooth repeater pivot-ably coupled with a saddle component, the saddle component further coupling the housing with the rear handle of the pistol grip in a slide-able fashion along a parallel axis to that of the barrel and the plunger, the tooth repeater adapted to engage and disengage with the plunger's threaded portion and incrementally move in only a forward direction along the plunger when engaged with the plunger's threaded portion; a rotatable dosage adjuster for selecting a desired dosage of injectable fluid to be forced out of the barrel during a full stroke of the ultra-low dose injection delivery system such that the plunger will advance only as far as the dosage adjuster will allow based on the desired setting before the tooth repeater engages the threaded portion of the plunger to prevent it from advancing any further during the rest of a stroke; and a clicker ring for providing an audible indication when a full stroke has been completed. ### Claim 6 (depends on 5) The ultra-low dose injection delivery system of claim 5 wherein the housing further comprises a release button for allowing and preventing the plunger from moving backwards by engaging and disengaging the tooth repeater. ### Claim 7 (depends on 1) The ultra-low dose injection delivery system of claim 1 wherein the needle coupling further comprises a needle nut for securing the needle coupling with the barrel. ### Claim 8 (depends on 7) The ultra-low dose injection delivery system of claim 7 wherein the needle coupling is a threaded quick coupling. ### Claim 9 (depends on 1) The ultra-low dose injection delivery system of claim 1 wherein the barrel further comprises a threaded quick coupling adapted to couple with a coupling component on the pistol grip.
